Colorado campaign spending tops $100M

State of play: Most of the $101 million spent through Oct. 23 is being funneled toward the battle for a Democratic supermajority in the state Legislature and a handful of high-profile ballot measures, an exclusive Axios analysis of the latest finance reports finds.

• Millions more continue to pour into campaign advertising and get-out-the-vote efforts, setting the stage for a flurry of activity in the final two weeks before the Nov. 5 election.

Zoom in: Billionaires and dark-money organizations continue to dominate the election, and Proposition 131 is driving most of the spending.

• Kent Thiry, the former DaVita CEO behind the election-related measure, is the largest individual donor at $4 million through the reporting period. 
• Two political committees he helped direct raised another $5.7 million for the cause.

The intrigue: Oil and gas company Chevron is the largest single corporate donor at roughly $1.8 million through the reporting period. The money went to electing Republicans in the state Senate and the Colorado Chamber's political committee.

• Last Friday, Chevron added a $500,000 donation to the Proposition 131 campaign.
